COOKING-RANGE.

Specification of Letters Patent.

Patented Apr. 29,1913.

Application filed January 27, 1912. Serial No. 673,719.

To all whom it may concern:

Be it. known that I, Josnri-r JOHN CART- WRIGI-IT, manager, a citizen ofGreat Britain, residing at Abbey Foregate, Shrewsbury, county of Salop,England, have invented. certain new and useful Improvements inCooking-Ranges, of which the following is a specification.

This invention comprises improvements relating to cooking ranges and theobject of the invention is to provide means for removing the hot gasesfrom above the hot plate where they are very objectionable to personssuperintending the cooking.

The hot gases from the grate and the hot plate and the steam from potsand kettles on the hot plate collect under the covering in plate andhang above the hot plate; to prevent this it has been proposed toprovide inlets in the back plate or coving leading into the chimney orfines but such inlets are found to impair the supply of air to the grateas they practically short circuit same. To obviate this it has beenproposed to draw these gases down and discharge them under the grate orover the front of the fire. 1

In accordance with my invention I draw the hot air and gases from thehot plate down to chambers or tubes in or at the sides of the fluebeneath the boiler and I preferably arrange and construct these chambersso that they may also serve as supports for the boiler.

I have found that by drawing the hot air and gases to the chambers inthe boiler flue such a powerful draft is promoted that hot air is drawnfrom the room in addition to the space about the covin'g, and theatmosphere of the entire room is cooled and rendered more pure. Further,the hot air which is drawn into the boiler flue brings a new supply ofoxygen into contact with the gases passing from the grate or oven fluesand more complete combustion of the gases is effected giving theadvantages of the heat for raising the temperature of the water in theboiler and the reduction of smoke.

In practice the side chambers in the boiler flue are found to check thevelocity and roar of the gases through the flues and to insure amoresteady and even working of the range promoting greater economy in fuelconsumption.

In order that the invention may be easily understood and readily carriedinto practice, I have appended hereunto two sheets of drawings on which:

Figure 1 is a front view of the upper portion of a range showing theapplication of my invention. Fig. 2 is a central vertical section of therange. Fig. 3 is a perspective view of the tube delivering the air intothe boiler fiuer Fig. 4 is a longitudinal sectional View of Fig. 3.

The coving plate a is perforated at suitable points for the insertion ofshort tubes 6 having flared mouths 0 through which the gases from thehot plate cl pass. The tubes 6 lead into a second tube 6 whichcommunicates by means of a down tube or tubes with the perforated tubeor tubes or chambers f whlch communicate with the flue beneath theboiler g. The tubes or chambers f are formed with perforations such ash, Fig. 4:. 1n the side for connection to the down tubes and on thesides remote therefrom are provided with a number of perforations 2'forming outlets for the hot air into the boiler flue. The hot air fromoff the hot plate d and the steam and other gases arising from utensilscontained thereon rise to the top of the recess underneath the coveringin plate and then are drawn through the flared months 0 of the tubes orchambers 72 into the boiler flue or grate bottom. I

The passage of the gaseous products of combustion along the boiler flueand chimney draws the hot air and gases from ofl the hot plate (Z intothe fine and thus keeps the temperature of the atmosphere around the topof the range at a comparatively low temperature. The hot air and gasesalso assist in heating the boiler instead of canslng inconvenience bytheir presence above the hot plate as in the case of an ordinary range.In the example shown upon the drawings there are three flared mouths cto conduct the hot air and gases away from the hot plate but I may varythis number if so desired.

I prefer to make the tubes or chambers f which deliver the heated airand gases to the boiler flue of square cross section but any suitablesection may be employed; if square or equivalent section is used howeverand the tubes are made of requisite strength they may form supports forthe boiler as here shown. The tubes may be of cast iron, fire clay orother suitable material.

In the foregoing description and in the claims appended hereunto it willbe understood that the term cooking ranges is intended to includecooking stoves whether portable or otherwise.

What I claim and desire to secure by Letters Patent then is:

.1. Cooking ranges and stoves having heating means and a hot plate abovesaid means, a boiler and a flue from said heating means to said boiler,means above said hot plate for collecting hot air and gases and meansfor conveying same to the boiler flue and distributing chambers arrangedwithin said flue through which chambers the hot air and gases from saidcollecting means are distributed in said flue.

2. Cooking ranges and stoves having heating meansvand a hot plate abovesaid means,

\ a boiler and a flue from said heating means to said boiler, meansabove said hot plate for collecting hot air and gases and means forconveying same to the boiler flue, chambers at the sides of said fluewhich form distributers for said gases and also form supports for saidboiler.

3. Cooking ranges and stoves having heating means and a hot plate abovesaid means, a boiler and a flue from said heating means to said boiler;means for collecting hot air and gases above said hot plate and passagesleading from said collect-ing means, distributing chambers in saidboiler flue to to this specification in the presence of two subscribingwitnesses, this 17th day of January, 1912.
